简化 0 = 0.5x3 + 3x2 + -8 重新排序条件: 0 = -8 + 3x2 + 0.5x3 解: 0 = -8 + 3x2 + 0.5x3 求解变量 'x'. 结合相似条件: 0 + 8 = 8 8 + -3x2 + -0.5x3 = -8 + 3x2 + 0.5x3 + 8 + -3x2 + -0.5x3 重新排序条件: 8 + -3x2 + -0.5x3 = -8 + 8 + 3x2 + -3x2 + 0.5x3 + -0.5x3 结合相似条件: -8 + 8 = 0 8 + -3x2 + -0.5x3 = 0 + 3x2 + -3x2 + 0.5x3 + -0.5x3 8 + -3x2 + -0.5x3 = 3x2 + -3x2 + 0.5x3 + -0.5x3 结合相似条件: 3x2 + -3x2 = 0 8 + -3x2 + -0.5x3 = 0 + 0.5x3 + -0.5x3 8 + -3x2 + -0.5x3 = 0.5x3 + -0.5x3 结合相似条件: 0.5x3 + -0.5x3 = 0.0 8 + -3x2 + -0.5x3 = 0.0 无法确定此方程的解.
